How to make Pearls from glutinous rice flour
-
Kneading dough
Next, gradually pour 260ml of boiling water into the bowl of flour mixture, then use a spoon to mix for about 3 minutes until the water cools down a bit, then use your hands to knead the dough.
After that, place the dough on a cutting board and knead it like you would for bread until the dough is smooth, elastic, and not sticky to your hands.
-
Shaping balls
Divide the dough into small round balls. Continue to roll the dough into a long shape, then use a knife to cut into small pieces and roll them into balls.
To prevent the tapioca pearls from sticking together, you need to prepare a bowl with a little tapioca starch, and when you finish shaping each ball, put it into the bowl of starch immediately.
-
Boiling tapioca pearls
First, place a pot of water on the stove and bring it to a boil. Once the water is boiling, add all the tapioca pearls and stir with a spoon to prevent them from sticking to the bottom of the pot.
Then, cover the pot, and when the water boils again, open the lid and stir once more before covering it again. During the boiling process, keep the heat high and monitor to prevent it from overflowing. Just boil for about 15 minutes, then turn off the stove and let it sit on the stove for another 15 minutes. If you boil over medium heat and keep the lid open, boil for 30 minutes and let it sit for 15 minutes.
Tip:- You should only boil as much as you plan to eat, especially when the tapioca pearls have been frozen; they should only be consumed in one go.
- To reduce the stickiness of the tapioca pearls, after letting them sit on the stove, you must scoop them out and rinse them briefly in clean water.
After that, place the tapioca pearls in a bowl, add 2 teaspoons of sugar, and wait for 10 minutes for the sugar to soak into the pearls before using them with milk tea (the sugar helps make the pearls sweeter and prevents them from swelling when stored in the refrigerator).
Note: To avoid the tapioca pearls becoming chewy when exposed to ice, do not soak the pearls in cold water for too long; just rinse them briefly to reduce stickiness. -
Final product
The tapioca pearls made from glutinous rice flour are chewy and have an attractive brown color. They have a light sweetness, with a fragrant aroma from pure cocoa powder that makes you love them more with each bite.
